近年来,随着城镇化建设的不断发展,一座座高楼大厦拔地而起。建筑施工外防护主要采用扣件式钢管脚手架,可是部分施工现场扣件式钢管脚手架搭设方式达不到规范化和科学化的安全防护作用。国家发布JGJ130—2011《建筑施工扣件式钢管脚手架安全技术规范》虽然严谨,但是仍有部分人员未充分理解其含义,因而使得外脚手架搭设存在重大的安全隐患。一、脚手架步距的选择笔者看过众多脚手架设计方案,其中对脚手架步距的选择不合理居多。可明显看出
In recent years, with the continuous development of urbanization, high-rise buildings have risen. The outer protection of the building construction mainly adopts the fastener-type steel pipe scaffolding, but some construction site fastener steel pipe scaffolding installation methods do not meet the standardization and scientific safety protection. The state issued the JGJ130-2011 “safety specification for fastener construction type steel pipe scaffolding for building construction,” although it is rigorous, but there are still some people who do not fully understand its meaning, which makes the external scaffolding erection there is a major security risk. First, the choice of scaffolding pace I have seen many scaffolding design options, including the unreasonable choice of scaffolding steps. Obviously visible
